One reason the first glass is so foamy is due to temperature differentials. Warm beer releases CO2 easier than cold beer. The temperature in the tower is higher than that in the refrigerator itself, resulting in the excess foaming until the colder beer from the keg makes it up through the tap.
Some folks have devised ways to force the colder air up into the tower using things like cooling fans from computer cases and whatnot.
